I'm certainly biased because my company (ServerPilot [serverpilot.io]) sells a service for PHP developers using DigitalOcean and other servers, but it does seem like PHP is making great progress in the past few years both in the language and in terms of a strong developer community. We're very glad to see PHP 5.3 EOL'd recently. To encourage adoption of 5.6, we've already packaged and added support for 5.6.
